Project Summary

Project Summary

This Wireless Mobile Battery Charger project is using technique of resonant magnetic coupling. The basic concept of this technique was applied in transformer construction. With this technique, the power from AC or DC can be transfer through the medium of magnetic field or air space. In this project, the method is divided into two major activities which is to purpose circuit construction and to fabricate the prototype. The result is to evaluate the distance of power that can be transferred using technique of resonant inductive coupling

Project Objectives

Project Objective

The main objective of the project is to study the fundamentals of wireless power transfer in terms of optimization of inductive as well as magnetic coils and the efficiency between transmitter an reciever coils.

We can also develop a device for  wireless power transfer.Basically the concept of wireless power transfer was realized by Nikolas Tesla.Wireless power transfer can make a remarkable change in the field of electrical engineering which eliminates the use conventional copper cables and current carrying wires.Based on this concept,the project is developed to transfer power within a small range.This Project  is used for charging the batteries those are physically not possible to be connected electrically such as pace makers.We also provide a Dc fan that runs through wireless power.

Project Implementation Method

The proposed system architecture consists of two sections namely  transmitter and receiver sections :-

Transmitter side

The transmitter section which starts with an input AC supply of 230V. Then stepdown transformer is used for reducing the input voltage.Actually,stepdown transformer converts the 230V AC supply into 12V AC supply.Then,the  bridge rectifier converts the AC supply to DC supply.Reason for using bridge rectifier is that we need only DC supply for charging the mobile .Next, the voltage regulator is used for reducing the repulsion in DC supply .Finally,theDCsupply is transferred to the transmitter coil. The wireless power transmitting coil would create an alternating magnetic field in the coil due to induction,to transmit energy.

Receiver Side

Receiver section consists of receiver coil.The AC current from the receiver coilis admitted for rectification and filters to convert AC into DC. Then,the DC supply is admitted to the DC regulator (7812) to change the DC supply to 12V DC. Next,the 12V DC is applied as an input to the PIC16F877A. Then the output is connected to  the mobile adapter.Since we are obtaining very low DCsupply, a mobile adapter is used.Using that adapter,mobile phone is admitted to the charging.

Technical Details of Final Deliverable

Technical Details of Final Deliverables

Wireless battery charging has many advantages in terms of  Convenience because users simply need to place the device requiring power on to a mat or other surface to allow the wireless Charging to take place.We believe that our contribution in this Work will successfully benefit society in terms of convenience, reduced wear of plugs and sockets,and application in medical Environments. Reduced efficiency is one of the key challenges in Wireless battery charging system due to resistive losses on the coil,stray coupling and etc.

And in our final Deliverables we will develop a prototype and charge multiple devices at a same time like small batteries,mobile phone batteries,biochemical devices etc.
